Hi All,
I keep getting the same error message each time I run "sudo apt-get upgrade" command: in my ubuntu 18.04.

I can't even run boot-repair.I get the same error while trying to install boot repair.
please support.

Ensure that there are no errors in /etc/default/grub
and /etc/grub.d/* files or please file a bug report with
/boot/grub/grub.cfg.new file attached.

There's probably a mismatch in grub config files. I suspect that your old /etc/default/grub still is in use and that it's not compatible with the new version of grub. As your error message said you have a new file called " grub.cfg.new" - compare that with /etc/default/grub.

Maybe you can post your /etc/default/grub here?

Hi Webaake,
Thank you for your prompt reply.

these is the grub file in /etc/default/grub

[deadflowr]

It shouldn't be i0apci but ioapic
From

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ivsr_i0apic{32}=00:14.0"
to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ivsr_ioapic{32}=00:14.0"
replace the zero with a small letter O, as in o as in own.
But that's just one thing, there may be others.

[webaake]

Thanks to deadflowr you can now try to rebuild it with:


sudo update-grub

and see what happens.

[richucj]

still getting the same syntax error

[deadflowr]

The /boot/grub/grub.cfg.new file has the exact issue, best to post it to pastebin rather than here since the file can be rather fat.
Just copy that file and paste it here: https://paste.ubuntu.com/
Then post a link to it for us.

Hope it make sense.

[richucj]

pls follow the link:https://paste.ubuntu.com/p/ZfmkrtBFxf/

[deadflowr]

Okay, looks like it's the wrong brackets.
should be [32] not (32)

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ivsr_ioapic{32}=00:14.0"
to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ivsr_ioapic[32]=00:14.0"

[richucj]

Thanks, deadflowr issue solved

[mörgæs]

Good, please mark the thread solved.
